CRUD limitations

• Read/Write models coupling problem
• Performance & Scalability limitations
• How CRUD limits Domain-driven design
• Exemplify by showing a social-network service implementation

Shifting to CQRS & Domain-driven design

• The CQRS concept
• CQRS benefits
• CQRS considerations (Eventual Consistency, Implementation Complexity)
• Modeling the Write Model using DDD patterns (Aggregates & Repositories)
• The CQRS flow
• Exemplify by implementing a CQRS-based social-network service (TypeScript)

Shifting to Event-sourcing

• The Event-sourcing data-persistence pattern
• Event-sourcing benefits & considerations
• How Event-sourcing leverages Domain-driven design
• How Event-sourcing is combined with CQRS
• Exemplify by implementing an Event-sourced CQRS-based social-network service (TypeScript).

‍

• Gain a deep insight into CQRS and Event-sourcing concepts.
• Understand how and why Event-sourcing and CQRS go hand-by-hand.
• Understand how Event-sourcing and CQRS help to leverage a Domain-driven approach.
• Learn how to model a Data-model using Domain-driven design principles & patterns.
• Practising on how to implement a Domain-driven Event-sourced CQRS-based social-network service using TypeScript (NodeJS).
